stochastic oscillator definition

Instead, traders should look to changes in the stochastic oscillator for clues about future trend shifts. Much like with any range-bound indicator, Overbought/Oversold conditions are a primary signal generated by the Stochastic Oscillator. The default thresholds are 20 for oversold and80 for overbought. These are typical levels but may not be suitable for all situations depending on the financial instrument being traded. Finding the correct levels comes with some experimentation as well as historical analysis.

stochastic oscillator definition

George Lane identified another form of divergence to predict bottoms or tops, dubbed “set-ups.” A bull set-up is basically the inverse of a bullish divergence. The underlying security forms a lower high, but the Stochastic Oscillator forms a higher high. Even though the stock could not exceed its prior high, the higher high in the Stochastic Oscillator shows strengthening upside momentum. The next decline is then expected to result in a tradable bottom. The Stochastic Oscillator moves between zero and one hundred, which makes 50 the centerline.

Overbought/Oversold Conditions

Or, even worse, many traders use their indicators in the wrong way and then make bad trading decisions that could have been easily avoided. As with other indicators, the Stochastic Oscillator also suffers from the problem of false signals. To calculate the slow stochastic, we find the 3-day SMA of the %K (essentially the same as the earlier %D).

Is MACD and stochastic the same?

Stochastic compares the asset's closing price to its price over a certain period of time while MACD shows two moving averages diverging and converging with one another. RSI, is the main momentum indicator traders would use in measuring the recent price changes.

With a downtrend in force, the Full Stochastic Oscillator was used to identify overbought readings to foreshadow a potential reversal. The shorter look-back period increases stochastic oscillator definition the sensitivity of the oscillator for more overbought readings. Notice that this less sensitive version did not become overbought in August, September, and October.

Example of the Stochastic Oscillator

A bearish divergence forms when price records a higher high, but the Stochastic Oscillator forms a lower high. This shows less upside momentum that could foreshadow a bearish reversal. Once a divergence takes hold, chartists should look for a confirmation to signal an actual reversal.

The oscillator tends to trend around a mean price level because it relies on recent price history, but it also adjusts when prices break out of price ranges. The stochastic indicator can be used by experienced traders and those learning technical analysis. The stochastic oscillator is built on the assumption that closing prices should confirm the current trend’s direction. However, the RSI tracks overbought and oversold levels by measuring the momentum of price movements. In other words, the RSI was designed to measure the speed of price movements, while the stochastic oscillator formula works best in consistent trading ranges. Typically, the stochastic indicator is employed by experienced traders and those learning technical analysis.

Stochastic RSI

The average true range is a market volatility indicator used in technical analysis. A crossover signal occurs when the two lines cross in the overbought or oversold region. A sell signal occurs when a decreasing %K line crosses below the %D line in the overbought region.

To calculate the stochastic oscillator, you subtract the low for the period from the up-to-date closing price. Then, you divide the total range for the period and multiply by 100.

Formula to calculate ATR

By comparing the closing price to previous price movements, the indicator attempts to predict price reversal points. While the adjustment to 85/15 does reduce the number of false signals, it may lead to traders missing some trading opportunities.
